## Long description

The HPE 879507-B21 is a 16 GB DDR4 2666 MHz memory module designed for entry-level HPE servers and compatible PCs. It is a 288-pin DIMM that operates at 1.2 V with CAS latency 19, offering reliable performance and efficient multitasking for small and medium business environments and remote or branch offices.
Advantages
HPE DDR4 Standard Memory combines performance and cost efficiency by using high-quality DRAM components and undergoing HPE’s testing and authentication to ensure compatibility with selected Gen9 and Gen10 server platforms. The module supports the performance characteristics of modern Intel processors, includes advanced error detection to reduce downtime and energy use, and is engineered for reliability and predictable behaviour in supported systems.
Suitable for
Upgrading memory in entry-level HPE Gen9 and Gen10 servers
Increasing RAM capacity in compatible workstations and PCs
Small and medium business servers, remote and branch office systems
When it may not be suitable
This module is intended for systems that accept 288-pin DDR4 DIMMs and operate at 1.2 V. It may not be suitable for systems that require ECC registered/buffered memory if your server requires those types, or for platforms that only support different speeds, voltages, or memory form factors. Always verify server compatibility before purchase.
Key specifications
Capacity: 16 GB
Memory type: DDR4
Speed: 2666 MHz
Form factor: 288-pin DIMM
Operating voltage: 1.2 V
CAS latency: 19
How to use
Power down the system and follow the server or motherboard manufacturer’s instructions for safe memory installation. Handle the DIMM by its edges, align the module with the memory slot keying, and press firmly until the retention clips engage. After installation, power on the system and confirm the new memory is recognized in the system firmware or operating system tools.
What to consider before purchase
Check that your server or motherboard supports 288-pin DDR4 DIMMs and 2666 MHz operation.
Confirm whether your system requires ECC, registered, or buffered modules and choose compatible memory.
Verify supported maximum memory per slot and overall system capacity limitations.
Usage recommendations
For optimal stability, install memory modules in matched pairs or according to the platform’s recommended channel population and update server firmware to the latest revision before deploying new memory.
